Slim 460mm LED Flush Ceiling Light 50W 4000K - White

The Mantra Slim is a 460mm diameter flush LED ceiling light with an integrated 50W LED delivering 4300 lumens at 4000K cool white. The entire fitting projects just 66mm from the ceiling, making it one of the slimmest flush-mount options for rooms with ceiling heights below 2.4m where a traditional pendant would hang too low.

Designed for kitchens, open-plan living spaces, hallways and multifunctional rooms needing clear task lighting, the Slim provides broad, even illumination with a 140° beam angle that reaches into corners without creating harsh shadows. The 4000K colour temperature sits between warm white (2700K-3000K) and daylight (5000K+), giving a neutral tone that works well where colour accuracy matters — food preparation, reading, makeup application — without the coldness of pure daylight LEDs.

The white frame and diffuser blend into white or off-white ceilings, leaving minimal visual interruption once installed. The acrylic diffuser spreads the 4300 lumens evenly across the 460mm diameter, avoiding the bright central hotspot and dim perimeter common in cheaper flush fittings. At 0.92kg the fitting is light enough to install onto plasterboard ceilings without additional bracing.

The LED is non-dimmable and runs on standard 220-240V mains with no external driver box to hide in the ceiling void. Mantra backs the Slim with a 3-year warranty covering LED failure and driver faults. Typical lifespan for the LED module is 25,000-30,000 hours at the stated 50W draw, translating to approximately 10 years of daily use at 8 hours per day.

Is the Slim suitable for low ceilings?

Yes. The 66mm projection makes the Slim one of the best options for rooms with ceiling heights below 2.4m where traditional pendants would hang too low or feel oppressive. The flush mount keeps the ceiling plane clean and maximises perceived room height.

Can it be dimmed?

No. The integrated LED is non-dimmable and should not be wired to a dimmer switch. If dimming is essential, consider Mantra's dimmable flush LED models or use a separate switched circuit.

What size room does 4300 lumens cover?

4300 lumens at 4000K provides sufficient ambient light for rooms up to approximately 18-20m² (a 4m x 5m kitchen or living room). Larger open-plan spaces benefit from two or three Slim fittings distributed across the ceiling to maintain even coverage.

What does 4000K cool white look like?

4000K sits between warm white (yellowish, 2700K-3000K) and daylight (blueish, 5000K+). It appears as a clean, neutral white with no strong yellow or blue cast, making it well-suited to modern kitchens, bathrooms and work areas where colour accuracy and clarity matter more than cosy warmth.
